Description

High-performance textile fabric cutting machine

Technical Field

The invention relates to the technical field of spinning, in particular to a high-performance textile fabric cutting machine.

Background

A cloth cutting and winding device is a complete set of equipment applied to the textile industry and used for cutting and winding cloth. The cloth cutting mainly comprises full cutting and interval cutting, wherein the full cutting refers to completely cutting off the cloth to separate the cloth into completely independent cloth sections, and the cloth cut and formed in the mode can be taken one by one in the subsequent use process due to the independent section forming, so that the convenience is realized; however, in this way, because the length of the cloth is short, effective rolling cannot be performed, and therefore, after cutting, post finishing is often performed by matching with manpower or machinery. The interval cutting means that the cloth is cut off in a dotted line shape at the position of a cut, and in the cutting mode, because the cloth sections are not completely disconnected and have certain connection points, the pulling force can also form certain transmission among the cloth sections, so that the mode is more convenient for subsequent rolling without manual or mechanical after-treatment; when the piece of cloth needs to be taken, the piece of cloth can be completely cut off only by simple manual cutting or mechanical cutting because the piece of cloth is cut off through the dotted line-shaped cut, so that the mode is more suitable for being applied to the industrial production of the piece of cloth.

However, the various cloth cutting and winding devices with intermittent cutting in the prior art still have the following problems, and need to be improved:

1. when the winding device winds cloth, after one cloth winding drum is wound, the cloth winding drum needs to be timely replaced, and when the existing cloth winding drum is replaced, the cloth winding drum is quite inconvenient, more parts need to be detached, and a large amount of time is wasted. Meanwhile, the replacement time of the cloth winding drum is long, so that the production efficiency is undoubtedly greatly influenced.

2. Because a cloth production line generally adopts a conveying mechanism to convey the cloth to unfold the line production, the cloth is in a moving state on the production line, and when the existing cutting device cuts the cloth, the conveying mechanism needs to be stopped firstly, namely the cloth is made to be static, and then the cloth is cut off by the cutting device. Because the conveying mechanism needs to be started and stopped frequently in this way, in other words, the conveying mechanism is in a continuous cycle of starting, braking and starting and braking, the energy consumption is increased, the service life of the conveying mechanism is shortened, and the improvement of the production efficiency is not facilitated.

3. At present cloth is at the in-process of cutting, owing to receive the elastic influence of cloth material, cloth tension has great difference on conveying mechanism, consequently, even conveying speed is confirmed with the cutting speed of shutting down, often still can not guarantee the accuracy of cloth section cutting, causes the cutting length of each section cloth to have certain error, and then leads to cloth section size irregularity, has influenced the quality of product. Therefore, the original technical idea in the prior art is to improve the cutting precision by reducing the conveying speed of the cloth and improving the matching precision between the timing of cutting the cutter and the conveying speed of the cloth, but the cutting device on the market at present does not make great progress in this respect due to the influence of the difficulty of technical implementation.

The feeding conveying mechanism 1 and the discharging conveying mechanism 3 convey the cloth through active rotation. The specific form of the feed conveyor 1 and the discharge conveyor 3 can refer to a roller conveyor or a nip roller conveyor which are commonly available on the market. Cutting mechanism 2 is used for carrying out the interval cutting to cloth, forms the accurate cutting opening of dotted line shape on making cloth, is convenient for subsequent cutting and takes. Winding mechanism 5 is used for carrying out the rolling winding to cloth, makes cloth be roll-like and collects on a winding drum 10 to the processing and transportation of convenient follow-up process are stored, guiding mechanism 4 is mainly used for guiding cloth towards winding mechanism 4 that ejection of compact conveying mechanism 3 seen off.

In combination with the three problems mentioned in the background, the present invention improves the existing cutting devices mainly from three major directions, which can be applied independently or in combination in the cutting devices mentioned above.

Firstly, in order to solve the problem of replacing the winding drum 10, as shown in fig. 2, the winding mechanism 5 of the present invention includes two first mounting side plates 6 arranged in parallel on the frame 0, wherein one first mounting side plate 6 is mounted on the frame 0 by welding or bolting, and the other first mounting side plate 6 is movably mounted on the frame 0, which is described in detail below.

Be provided with rolling pivot 7 between the first installation curb plate 6, the one end of rolling pivot 7 passes a first installation curb plate 6 and is connected with the fixed rolling motor 8 transmission that sets up on first installation curb plate 6, drives its rotation through rolling motor 8. The other end of the rolling rotating shaft 7 penetrates through a rotating shaft mounting hole 9 on the other first mounting side plate 6 and is in rotating fit with the first mounting side plate 6. As shown in fig. 2, that is, the right end of the winding shaft 7 is fitted into the shaft fitting hole 9 of the right first fitting side plate 6. The lower end of the first installation plate side on the side far away from the rolling motor 8 on the rack 0 is hinged with the rack 0 through a first hinge seat 11, and the first installation side plate 6 can swing around the first hinge seat 11 under the driving of the side plate adjusting assembly, so that the rotating shaft installation hole 9 on the first installation side plate 6 is separated from the rolling rotating shaft 7 or is sleeved on the rolling rotating shaft 7. In this way, the first mounting side plate 6 on the right side can be disengaged from the winding rotating shaft 7 by the rotation of the first mounting side plate 6, so that the winding drum 10 on the first mounting side plate can be conveniently taken down.

The specific structure of curb plate adjusting part is more, and it can be the accommodate motor who is connected with the articulated axle of first articulated seat 11 and first installation curb plate 6 for example, and it is rotatory to drive the articulated axle through the motor rotation, and then drives first installation curb plate 6 and rotate. As shown in fig. 2 and 3, the side plate adjusting assembly may further include a second hinge base 12 mounted on the frame 0 at one side of the first hinge base 11, and a third hinge base 13 mounted at a side of the first mounting side plate 6. An adjusting cylinder 14 is arranged between the second hinge base 12 and the third hinge base 13, and two ends of the adjusting cylinder 14 are hinged to the second hinge base 12 and the third hinge base 13 respectively. The first mounting side plate 6 is driven to rotate around the hinge shaft of the first hinge base 11 by the extension and contraction of the adjusting cylinder 14. Of course, other configurations of the side plate adjustment assembly are possible while performing the same function.

The winding rotating shaft 7 is sleeved with a winding drum 10 and a locking component for fixing the winding drum 10 on the winding rotating shaft 7. The winding mechanism 5 directly fixes the winding drum 10 and the winding rotating shaft 7 through the locking component, so that the winding drum 10 can rotate along with the winding rotating shaft 7 when the winding rotating shaft 7 rotates. The simplest locking component is a bolt, bolt holes are formed in the winding drum 10 and the winding rotating shaft 7, and the bolt can be inserted into the bolt holes to directly fix the winding drum and the winding rotating shaft. This approach, while simple, is relatively less stable.

For this purpose, the present invention may also be better implemented by combining fig. 3-6, wherein the winding drum 10 includes a drum body 15, and end discs 16 are fixedly disposed at two ends of the drum body 15 for limiting the positions of two sides of the cloth, although the end discs 16 may be adjustable structures, so as to facilitate the position adjustment on the drum body 15, thereby adapting to the cloth with different widths. The center of barrel 15 is provided with sleeve 17, the center of sleeve 17 is provided with the centre bore 18 with rolling pivot 7 looks adaptation along the axial, evenly be provided with a plurality of first pole holes 19 parallel with centre bore 18 on the sleeve 17 lateral wall of centre bore 18 week side, the winding drum 10 overlaps on rolling pivot 7 through centre bore 18 cover. After the mode is adopted, only the central hole 18 and the winding rotating shaft 7 need to be aligned, the winding drum 10 can be directly sleeved on the winding rotating shaft 7 through the sleeve 17, two ends of the central hole 18 can be arranged in a horn shape, alignment is more convenient, the horn-shaped structure is simpler, and the horn-shaped structure is not directly shown in the figure of the invention.

The locking assembly comprises a fixed disc 20, an inserting disc 21 and a leaning disc 22, the fixed disc 20 is fixedly arranged at one end, close to the winding motor 8, of the winding drum 10, namely on the winding rotating shaft 7 corresponding to the left end in fig. 2, a plurality of second rod holes 23 are uniformly formed in the fixed disc 20, and the second rod holes 23 are identical to the first rod holes 19 in aperture and correspond to the first rod holes 19 in one-to-one mode. The plug-in board 21 is sleeved on the other end of the winding drum 10, that is, the winding rotating shaft 7 corresponding to the right end in fig. 2, and a plurality of plug-in rods 24 extending along the length direction of the winding drum 10 are uniformly arranged on one surface of the plug-in board 21 close to the winding drum 10, as shown in fig. 5, the plug-in rods 24 are four and circular, of course, the number of the plug-in rods 24 can be more or less, and the shape can be designed into other shapes. The inserting rods 24 are matched with the first rod holes 19 and correspondingly penetrate through the first rod holes 19 and the second rod holes 23 one by one. The abutting disc 22 is sleeved on the winding rotating shaft 7 on one side of the inserting disc 21 far away from the winding drum 10 and forms threaded fit with the winding rotating shaft 7.

In use, the abutment disc 22 is rotated to remove the abutment disc 22, the plug disc 21 can then be removed, and the take-up spool 10 can be removed. This way on the one hand the stability of the fixation is better and on the other hand the operation is more convenient. In order to facilitate the rotation of the abutting disc 22, a plurality of handles 25 extending in the radial direction of the abutting disc 22 are uniformly arranged on the circumferential surface of the abutting disc 22.

When the winding mechanism 5 is used and the winding drum 10 needs to be replaced, firstly, the side plate driving assembly is utilized to drive the first mounting side plate 6 to rotate around the first hinge seat 11, so that the rotating shaft mounting hole 9 on the first mounting side plate 6 is separated from the end part of the winding rotating shaft 7, and then the locking assembly is taken down, so that the winding drum 10 can be pulled out from the overhanging end of the winding rotating shaft 7 along the length direction for replacement. After a new winding drum 10 is mounted on the winding rotating shaft 7, the locking assembly is mounted again, the side plate driving assembly drives the first mounting side plate 6 to reset, the rotating shaft mounting hole 9 on the side plate is sleeved outside the winding rotating shaft 7 again, and the end part of the winding rotating shaft 7 is supported. Compared with the traditional winding mechanism, the winding mechanism has the advantages that the winding drum 10 is more convenient to replace, and the winding mechanism works more stably under a normal winding working state.

The cutting mechanism is improved, the traditional shutdown cutting mode is abandoned, the original following cutting mode is adopted, and the online cutting without shutdown is realized. As shown in fig. 1, the cutting mechanism 2 of the present invention includes a cutting assembly for cutting the cloth and a sliding assembly capable of driving the cutting assembly to move synchronously with the cloth, both of which are controlled by a general controller of the device, i.e., an industrial personal computer.

The sliding assembly comprises an installation guide rail 26 and a walking platform 27 arranged on the installation guide rail 26, wherein the installation guide rail 26 is fixedly arranged on the rack 0 between the feeding conveying mechanism 1 and the discharging conveying mechanism 3 and extends along the length direction of the rack 0. The lower part of the walking platform 27 is provided with a slide block 28 matched with the mounting guide rail 26, a driving screw 29 is arranged in the mounting guide rail 26, and one end of the driving screw 29 is in transmission connection with a first stepping motor 30. The slide block 28 is clamped in the mounting guide rail 26 and sleeved on the driving lead screw 29 to form threaded fit with the driving lead screw 29. The fixed mounting groove 31 that is provided with the U-shaped in the top of walking platform 27, the cutting assembly sets up in mounting groove 31, for the intensity that improves mounting groove 31, be provided with triangle reinforcing plate 69 between the bottom surface of the side of slider 28 and mounting groove 31. Of course, the matching structure of the sliding block 28, the mounting rail 26, the walking platform 27 and the driving screw 29 in fig. 7 is only a simplest matching form, and those skilled in the art can also improve the matching structure by combining with the prior art on the basis of the simplest matching form, so as to achieve the purpose of improving the matching precision and stability.

The cutting assembly of the cutting mechanism is arranged on the sliding assembly, the first stepping motor 30 can sequentially drive the driving screw 29, the sliding block 28, the walking platform 27 and the mounting groove 31 to move along the length direction of the mounting guide rail 26, so that the cutting assembly arranged in the mounting groove 31 is driven to move along with the conveying speed of the cloth, the cutting assembly cuts the cloth while moving along with the cloth, and after the cutting is finished, the sliding assembly drives the cutting assembly to reset again to enter the next working cycle. Compared with the traditional cutting mode, the invention does not need to interrupt the conveying of the cloth when cutting, realizes the online cutting without stopping, avoids the influence on the self caused by the repeated starting and stopping of the feeding conveying mechanism 1 and the discharging conveying mechanism 3 on one hand, and prolongs the service life of the whole machine; on the other hand, the machine does not need to be stopped, so that the cloth production efficiency is greatly improved.

The cutting assembly has more specific forms, such as: the cutting assembly can be composed of a cutter frame, a cutter holder and a cutting knife, wherein the cutter frame and the cutter holder are arranged up and down, the cutting knife is arranged at the bottom of the cutter frame, cloth passes through the cutter frame and the cutter holder, the cutter frame moves up and down under the driving of a cylinder, a hydraulic cylinder and other motive power components, so that the cloth on the cutter holder is cut, and the cutting knife can adopt a serrated design, so that the cloth can be cut at intervals conveniently. However, in this way, in order not to affect the feeding of the cloth, the top surface of the tool holder usually needs to have a certain clearance from the cloth, which results in a large downward pressure on the cloth during the cutting process of the cutting knife, and the downward pressure may cause the cloth to deform, thereby affecting the cutting precision.

Therefore, the cloth is better fixed in a vertical clamping mode and then cut. That is, the cutting assembly of the present invention clamps and fixes the cloth on the original conveying path of the cloth by folding and separating the upper clamp plate 36 and the lower clamp plate 37 up and down, and then performs cutting. Referring to fig. 7 and 8, the cutting assembly includes two mounting seats 32 symmetrically disposed on two inner sidewalls of the mounting groove 31, an upper transverse plate 33 and a lower transverse plate 34 extending along a width direction of the cloth are disposed between the two mounting seats 32, and two ends of the upper transverse plate 33 and the lower transverse plate 34 are respectively fixedly connected to the mounting seats 32 through a fixing connecting rod 35 to form a frame-shaped structure. An upper clamping plate 36 and a lower clamping plate 37 which extend along the width direction of the cloth are further arranged between the upper transverse plate 33 and the lower transverse plate 34, and the cloth is located between the upper clamping plate 36 and the lower clamping plate 37. According to the invention, the cloth is clamped on the premise of not changing the original conveying path of the cloth as much as possible by moving the upper clamping plate 36 and the lower clamping plate 37.

The specific driving manner is that a lateral electric push rod 38 is arranged on one side of the mounting seat 32 facing the upper clamping plate 36 and the lower clamping plate 37, an output end of the electric push rod 38 faces the center of the mounting groove 31, namely, the right side in fig. 8, and a connecting plate 39 is arranged at an end of the electric push rod 38. Be provided with first engaging lug 40 on the connecting plate 39, the both ends of punch holder 36 and lower plate 37 all are provided with second engaging lug 41, be provided with drive connecting rod 42 between first engaging lug 40 and the second engaging lug 41, drive connecting rod 42's both ends are articulated with first engaging lug 40 and second engaging lug 41 respectively. When the electric push rod 38 extends and contracts, the upper clamping plate 36 and the lower clamping plate 37 can be driven to move up and down through the driving connecting rod 42, and therefore folding or separation is achieved. Of course, in order to further improve the up-and-down movement stability of the upper clamping plate 36 and the lower clamping plate 37, the two ends of the two can be sleeved in the two vertical guide rods together, and the guide rods can be guided up and down through the guide rods, and the guide rods can be directly and fixedly connected with the upper transverse plate 33 and the lower transverse plate 34.

Considering that the efficiency of the conversion of the driving force by the driving link 42 is relatively low when the upper and

lower clamping plates

36 and 37 are at the opening limit position, it is preferable that, as shown in fig. 8 and 9, swing links 61 are further provided above and below the connecting plate 39, and the middle section of the swing link 61 is hinged to a short rod 62 fixedly provided on the fixed link 35. The upper and lower sides of the connecting plate 39 are bent toward the mounting seat 32 to form inclined bent portions 63. One end of the swing link 61 is provided with a hook 64, and the other end of the swing link 61 inclines towards the bent part 63 on the connecting plate 39 and contacts with the bent part 63. Contact plates 65 are further arranged at two ends of the upper transverse plate 33 and the lower transverse plate 34, and the hook heads 64 are in contact with the contact plates 65. When the electric push rod 38 drives the connecting plate 39 to move, the bent part 63 on the upper side and the lower side of the connecting plate 39 drives the swing rod 61 to rotate, and then the rotating hook 64 applies a pressure to the hunger contact plate 65, and the upper clamping plate 36 and the lower clamping plate 37 are driven to move through the contact plate 65.

In the same way, considering that the conversion efficiency of the driving force by the driving connecting rod 42 is relatively low when the upper clamping plate 36 and the lower clamping plate 37 are at the closed limit position, the bottom parts of the two ends of the upper clamping plate 36 are also provided with spring holes 66, and the bottom parts of the two ends of the lower clamping plate 37 are provided with push rods 67 corresponding to the positions of the spring holes 66. Contact pieces are arranged in the spring holes 66, and ejection springs 68 are arranged between the contact pieces and the hole bottoms of the spring holes 66. When the upper and lower clamping plates are closed, the ejection spring 68 is compressed to continue elastic potential energy, and when the upper and lower clamping plates need to be opened, on one hand, power is transmitted through the driving connecting rod 42, and on the other hand, the continuous elastic potential energy of the ejection spring 68 is released, so that the upper and lower clamping plates can be opened.

The center of the bottom surface of the upper clamping plate 36 is provided with a cutter mounting hole 43, the cutter mounting hole 43 extends along the length direction of the upper clamping plate 36, and a cutting cutter 53 capable of cutting cloth at intervals is arranged in the cutter mounting hole 43. According to the invention, a cutter is directly arranged in the cutter mounting hole 43 of the upper clamping plate 36, a cutter seat is arranged on the lower clamping plate 37, the cutter adopts a saw-tooth shape, a cutter passing groove matched with the saw-tooth shape is arranged on the cutter seat, and when the upper clamping plate and the lower clamping plate are folded, the saw-tooth-shaped cutter directly cuts the cloth at intervals, so that a virtual line-shaped cut is formed. However, in this way, the cutting operation completely depends on the downward pressure of the cutting knife, and the pressure is relatively high, so that the cloth is easily damaged if the cloth cannot be penetrated in time under the condition of relatively good toughness and elasticity of the cloth. For this reason, the present invention may be further configured such that the cutting blade 53 is an ultrasonic cutting blade. Utilize ultrasonic cutting knife direct realization to the cutting of cloth, because ultrasonic cutting knife's characteristic is not only convenient for pierce through cloth more, form regular incision, also can realize the banding to the notched simultaneously.

However, compared with a common cutter, the ultrasonic cutting knife has higher cost, and if the hole position of each virtual line-shaped cutting opening is penetrated by one ultrasonic cutting knife, a large amount of equipment cost is consumed. Therefore, the present invention may be further configured such that a screw rod 44 is disposed in the tool mounting hole 43 along the length direction, one end of the screw rod 44 is mounted on a side wall of one end of the tool mounting hole 43 through a bearing, and the other end of the screw rod 44 is in transmission connection with a second stepping motor 45 fixedly disposed on a side wall of the other end of the tool mounting hole 43. The lead screw 44 is further sleeved with a moving block 46, and the moving block 46 and the lead screw 44 form threaded fit. The second stepping motor 45 can drive the lead screw 44 to move, and further drive the moving block 46 to move, one ultrasonic cutting knife is installed on the moving block 46, and the ultrasonic cutting knife is driven by the moving block 46 to realize interval cutting of the dotted line shape. In order to meet the cutting requirements of the various dotted lines, the driver blade 42 may also be of a replaceable construction, i.e., the driver blade 52 may be removably attached within the tool mounting hole 43.
